Listen for Changes In Cassandra Datastore?

Question

I wonder if it is possible to add a listener to Cassandra getting the table and the primary key for changed entries? It would be great to have such a mechanism.

Answer 1

Are you looking for something like triggers?

A database trigger is procedural code that is automatically executed in response to certain events on a particular table or view in a database. The trigger is mostly used for maintaining the integrity of the information on the database. For example, when a new record (representing a new worker) is added to the employees table, new records should also be created in the tables of the taxes, vacations and salaries.
